Personally I despise FNAF, it was good and fun when it first came out and now people are just taking it too far. I've also had a lot of issues with the characters at random attacking me when I enter Ficho or when there is no one else in bonfire bar me and them (excuse the random TLK rp'ers that rarely do anything on local) I also don't believe a lot of its appropriate, the few I come across tend to be aggressive if you even come within a meter of them.
I don't like them at in all honesty, great if your having fun. But don't involve other people in your madness
